[Freeswitch-users] TLS stops when a call is enabled

[Aina Mestre]

Good morning,

I have just corrected what you comment, but that didn’t solve my problem. My problem is that the SIP protocol is not encrypted so even if the RTP is encrypted, you can see all INVITE information on wireshark. I tryed to solve it adding in the dialplan
<action application="bridge" data="{${t38}}${mydialbridge};transport=tls"/>)

But the result I get is an error that says “TLS not supported by profile”

Thank you in advance

This is a variable:

NOT A PARAM.

Good morning,

I’m trying to configure SRTP with TLS on Freeswitch. I already have SRTP, and I can establish a conversation with TLS, but when I make a call, it says “encrypted alert” and the TLS conversation stops sending the INVITE in TCP. I have been looking for some solutions and it states that the problema may be that the certificate is not properly configured or that TLS is not properly configured. It is imposible that the certificate has any problems because I currently get TLS untill the call starts.

Here it is the configuration on my profile:


        <param name='rtp_secure_media' value='mandatory: AES_CM_128_HMAC_SHA1_80'/>
        <param name='bind-params" value="tls"/>
        <param name='tls-version' value='tlsv1'/>
        <param name='register-transport' value='tls'/>
        <param name="register" value="false"/>
        <param name="transport" value="tls"/>
        <param name="tls" value="$${internal_ssl_enable}"/>
        <param name="tls-only" value="true"/>
        <param name="tls-bind-params" value="transport=tls"/>
        <param name="tls-sip-port" value="$${internal_tls_port}"/>
        <param name="tls-cert-dir" value="/usr/local/freeswitch/conf"/>
        <param name="tls-verify-date" value="true"/>
        <param name="tls-verify-policy" value="none"/>
        <param name="tls-version" value="$${sip_tls_version}"/>
        <param name="tls-ciphers" value="$${sip_tls_ciphers}"/>
        <param name="contact-params" value="tport=tls"/>
        <param name="ws-binding" value="XX.XX.XX.XX:5061"/>

Also, I would like to make another observation: when I configure the bridge has transport=TLS ( <action application="bridge" data="{${t38}}${mydialbridge};transport=tls"/>) in the dialplan, the debug says “TLS not supported by profile”

Thank you for taking the time to deal with my queries

Kind regards.
